Buster is а 10-yeаr-оld mаle neutered Dоmestic Shоrt-haired cat. He presents for a tail amputation after suffering a traumatic de-gloving injury when his tail was shut in a truck door earlier that day. Buster’s physical exam is normal, except for the tail. He has been eating and drinking normally, his pre-anesthetic diagnostics are all within normal limits, and he has no history of medical problems. Unfortunately, Buster has run out of “kitty minutes” and is now hissing and swatting. He will need sedation for IV catheter placement prior to induction of anesthesia. Which of the following premedication combinations is the optimal choice for intramuscular injection?
